[feature-request] New Rating Category for Longer Time Controls

+1 from me. I would also like to see tournaments with longer time controls

Handling the ratings if you split the category is straightforward enough. You simply set all players to 1500 in both categories and then compute the result of each game in the history in sequence and assign ratings accordingly -- sort of like having the computer replay the games. The result will be exactly the same as if there had always been two categories.

Far more important to me, though, is I would like to see a "quick pairing" setting with longer time controls. I am not a fast thinker and 15+15 is not nearly enough for me to consider my moves properly. It always sucks to reach an interesting position and have to rush it due to time pressure. I often find myself thinking, "There's probably a good tactic here, but there's no way I have enough time to find it!" Sure, I can queue up for a game with longer time controls... but it'd probably take a while for anyone to even notice my game exists, because most people are probably queuing up with quick pairing and not even looking at the lobby.

#42 and how much time you think it would take? I guess you are a lucky guy living in an era of quantum computers...

Interesting idea but I don't know if it would be that easy (maybe it is).

I was thinking everyone would keep their current classical as their rapid, and everyone will start the "new classical" at 1500. Just like a new variant.

There should be an additional RAPID mode. Games with 5+5 or 3+8 time control currently belong to the CLASSICAL mode; which is quite strange...

@furrykef - your suggestion about the rating won't work. All ratings depend also on the rating of your opponents. That is the reason why many chess sites do not even refund rating loss when you forfeited against a cheater.

Anyway - do not care so much about ratings of the past. Make a new category, let everybody (even those who previously played, say, 30+10 games) start at 1500, and let us see how it goes.

@Sybotes: but your opponents' ratings would be adjusted too. So long as the games are processed in chronological order, it will be as if they had been played that way in the first place.

Think about it: every player's rating is simply a function of the list of game results. If the ratings database table were deleted, we could reconstruct it by simply "replaying" all rated games -- not the actual moves, just the results -- in order. (Care would have to be taken to ensure the players' RDs before each game remain the same as they were when the games were played the first time around; this would involve checking the timestamps for each game. But it should be doable.)

What I propose is doing exactly this except splitting the classical category into two categories first.

#48: you're ignoring what #43 implied, namely that this would take an ABSURD amount of time to run. It's simply impractical. Yes in theory this works, but in practice it doesn't.

Sorry, I'd missed post #43.

Maybe I'm hopelessly naïve, but why does it take so long to process the results of 215 million games? (And that's assuming all games are rated and all of them are currently classified as classical; I'd guess the actual number is an order of magnitude less.) If it takes 1 millisecond to process a game, then, according to my calculations, it will take 60 hours to do them all -- not exactly an insurmountable amount of time. Would it really take more than a millisecond to process each game?
